WORST SERVICE OF MY LIFE

I am very unhappy of the service I received and Kia Silverton from the sales person and the branch manager. I just bought a car from there a few weeks ago only to find out that the spare wheel they gave me is old and had to be repaired. Upon informing the branch of the above matter their response was that I bought a demo car and should not expect to get a new or proper spare wheel, bare in mind that the car was only 9000kms when i bought it. I would never advise anyone to buy a car from them and to top it off I reported this to Kia Motors SA and ever since they said they would call me of which they didn't I am still waiting for them to attend to this matter.
